Never mind, I got it on my own:
/**
* Perform calculation solely upon re-entered width and height if a
calculation percentage was not entered nor chosen. Can be called
statically
*
* @access protected
* @param int $width (reference)
* @param int $height (reference)
* @param int $origWidth
* @param int $origHeight
* @return array $dimArray Array consisting of recalculated width and
height
*/
function &calculate_width_and_height(&$width, &$height, $origWidth,
$origHeight) {
if ((int)$origWidth === 0 || (int)$origHeight === 0) return
array($width, $height); // TO AVOID DIVISION BY ZERO
if ((int)$origWidth !== (int)$width && (int)$origHeight !==
(int)$height) return array($width, $height); // NO NEED TO CALCULATE
SINCE CHANGING ALL DIMENSIONS
if ((int)$origWidth !== (int)$width) $height = $width * ($origHeight
/ $origWidth);
if ((int)$origHeight !== (int)$height) $width = $height * ($origWidth
/ $origHeight);
return array(floor($width), floor($height));
}
